Review: COLORADO DOG 100% Natural Flea & Tick Prevention for Dogs
Our team at Petscarelab rates the COLORADO DOG 100% Natural Flea & Tick Prevention for Dogs as a reliable, daily oral repellent that provides ongoing, chemical-free protection that is completely safe for multi-pet households.
Active Ingredients & Efficacy
Let's break down the science behind this 100% natural chewable. Unlike harsh chemical treatments that rely on neurotoxins like Permethrin to kill adult fleas on contact, this formula works from the inside out. It uses a strategic blend of brewer's yeast, a safe dose of garlic, and a vitamin complex to literally change how your dog smells to parasites. The chews mask your pup's natural carbon dioxide emissions, making them virtually invisible to biting pests.
Active essential oils like lemongrass and cedarwood oil add a second layer of defense. Because this is a daily natural repellent, it doesn't break the egg-larvae cycle like chemical IGRs (Insect Growth Regulators) such as Pyriproxyfen would. Instead, it excels at keeping adult fleas and ticks from hitching a ride in the first place while you are out hiking or at the dog park.
Application & Safety
Say goodbye to parting your dog's hair, applying messy liquid topicals, and waiting 24 hours for the grease to dry. I love that you just toss your dog a bacon-flavored soft chew instead. The daily dosage is straightforward and based on weight: 2 chews for dogs under 30 lbs, stepping up to 5 chews for giant breeds over 90 lbs.
Because it is entirely free of corn, soy, sugar, and synthetic chemicals, you don't have to worry about the strict safety protocols required by topical liquids. There are no ventilation requirements, no toxic wet spots on the floor, and no need to keep your children away from the dog while a treatment dries.
Environmental Control Alternatives: Targeted Sprays vs. Room Foggers/Bombs
If you skipped prevention and are currently dealing with a massive active infestation in your house, you will need environmental controls alongside these preventative chews. Here is how traditional indoor treatments compare when you need to clear your home:
Real-World Considerations
Let's talk about the practical side of feeding these daily. At $17.99 for a 120-count jar, the value is fantastic, but there is a catch: picky eaters. I noticed the savory bacon scent is distinct, yet some dogs simply refuse to eat them whole. If your dog turns their nose up, you'll need to crumble the soft chews into their regular meals. Adding a little warm water or fish oil to make a quick gravy works wonders.
On the upside, feeding an oral chew means absolutely zero staining risks to your expensive carpets or furniture—a massive win over greasy topical oils. Keep in mind, if you are actively fighting an existing home infestation, these chews are repellents, not exterminators. You will still need to put in the manual labor of daily vacuuming and washing all bedding in hot water to clear out existing eggs and larvae.
Final Verdict
Who it’s for: Pet parents looking for a completely natural, chemical-free daily defense for active outdoor dogs, and anyone who hates the messy residue of traditional topical drops.
Who it’s NOT for: Extremely picky dogs that refuse chewable supplements, or owners currently battling a severe, active flea infestation that requires immediate chemical knockdown power.
